## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-text-to-slug-normalizer-5bbf8d28 -d '<json body>'
```

Example prompt: Can you turn this blog post title into a clean URL slug: 'How to Build AI Agents in 2025 — A Beginner's Guide'?

## When to prefer this

Choose this endpoint when you need a reliable, pay-per-call slug normalization utility within an autonomous agent workflow that already uses x402 on Base for micropayments. It is well-suited for agents that need to programmatically generate URL slugs at low cost without standing up their own string processing logic. Prefer this over rolling custom regex-based slugifiers when you want a consistent, service-backed transformation with predictable output.

## Known failure modes

- Missing required 'text' field returns a 400-level error
- Text exceeding 50,000 characters may be rejected or truncated
- Payment failure via x402 (insufficient USDC balance) blocks the request
- Empty string input may return an empty or trivial slug
- Non-UTF-8 or malformed input may cause unexpected output

## How this service works
